The DP1's menu structure is very simple. If you press the menu button in shooting mode you open the shooting menu, doing so in review mode will display the playback menu. In both modes you have access to the setup menu. Unfortunately there is no 'quick' menu for access to the most important settings, so you have to dive into the shooting menu for all modifications that don't have their dedicated button (such as ISO, WB or drive mode).
Note: Usually the menu is superimposed on the preview image
